FORMING MECHANISM.

Specification of Letters Patent. Patented Sept. 26, 1916.

Application filed February 6, 1914. Serial No. 816,969.

To all whom it may concern:

Be it known that I, Goorasr P. SCHMIDT, a citizen of'the United States, residing in the borough of the Bronx, in the county of Bronx and State of New York, have invented certain ncw and useful Improvements in Forming Mechanism, of which the following is a s ccil'ication, reference being had therein to tie accompanying drawing.

My invention relates to improvements in formin machines and is articularly well adapte for use and is ilustrated 1n the accompanying drawings in its application to a device or formm ovals, rings and other suitable shapes for racelets or similar articles.

In said drawings, Figure 1 is a longitudinal view, partly in cross section, illustrating an ap lication of my invention. Fig. is a view coking from left to ri ht at Fig. 1 with parts in cross section an parts broken away, and Fig. 3 is an enlarged detail of one of the gui es partly in cross section.

4 indicates a suitable table or support upon which the machine ismounted in any suitable manner as shown.

5 represents the frame of the machine.

6 is the shaft upon which is mounted a suitable transmission or pinion such as 7 and which may be provided with a handle such as 8 or which may be driven by power or other suitable means.

9 is another shaft also carrying a pinion such as 10 suitably secured thereto. This shaft is pivotally mounted within the bearing 11 which is provided with suitable trun ions such as 12 which give the shaft 9 free om to move up and down at the leftward extremity. The said shaft isin turn projected leftwardly from the bearing 11 by the coil spring 13 which bears against the pinion 10 as shown and against the shoulder or seating 14 ofthe bearing 11.

15 is a suitable collar or binder provided with the usual set screw or other means such as 16 and adapted to engage the end of the shaft 9 as shown so that the adjustment of the shaft 9 longitudinally within the frame 5 is secured by the clamp or binder 15 and the coil spring 13.

17 is a suitable collar upon the drive shaft 6 which also serves to keep said shaft 6 in position. mounted the rollers or forms 19-5-20 'respectively, said rollers beinpiaheld inposition 'on said shaftsbyanyauita lemeans such as Upon the shafts 6' and. 9 are the nuts 21--22 respectively. The proper separation of the rollers or forms 1920 it will be observed is determined by the ad- 'usting handle 23 in the top of the frame 5.

he base of this adjusting handle it will be observed engages the slide bearing 24 which carries the shaft 9, said slide bearing being preferably mounted upon suitable resilient means such as the spring 25.

Referring now to Fi 2, it will be observed that the cam 18 shown in dotted out line is retained in contact with the oscillating member 26 mounted upon the pin 27, udjustably secured within the slot 28 by any suitable means such as the nut 29. The other end of the oscillating member 26 it will be observed is provided with an adjustable screw such as 30 which may be secured in any suitable manner as by the binding nut 31, and, 32 it will be observed indicates a suitable scale beneath the finger 33 upon the pin or spindle 27, so that the insertion or movement of the member 26 may be readily calculated and registered.

34 indicates another member mounted to ride upon the-shaft 6 as shown, said bearing being adapted to be oscillated thereupon by the member 26 through the medium of the screw 30. The said member 34. it will be observed is provided with suitable dovetailed engaging means such as 35 shown in dotted outline for slidably connecting the forming member 36, adapted to slide thereupon by adjustment of the thumb screw 37 within the swinging bracket 38 mounted upon the screw 39 in the member 34.. Said screw 89 it will also be observed is provided with suitable resilient means such as 40 serving to retain the pin.41 within the recess 42 in the bracket 38, so that when the bracket 38 is swung up into the position as shown in Fig. 2, it is normally retained in said position by virtue of the engagement between the pin 41 and recess 42 within said bracket.

It will also be observed that when it is desired to remove or replace the tool 36 it is only necessary to throw the bracket in the direction of the observer and after the tool 36 has been removed or replaced the bracket may readily be restored in position and the adjusting screw 37 brought up against the tool 36' to retain it in proper place.

The broken cross section of the guide top plate or cap indicated by the reference character 43 is illustrated to better advantage on an enlarged scale in Fig. 8 wherein he same is shown on the line 33 of Fig. 2 looking from right to left at said Fig. 2.

44: indicates a plate or other suitable means for carrying the bracket or table 49 which supports the guide mechanism upon the frame of the machine.

45%6 indicate guides between which a suitable strip or ribbon of material such as 47 may be introduced beneath the top plate or cap 43. After passing beneath said plate 4-3 the strip of metal or other material of course is engaged between the rollers 19-20 and is formed according to the shape to be determined by said rollers. Upon emerging from between said rollers the strip of metal is then met by the tool 36, the adjustment of which with reference to the rollers 1920 determines the character of curvature to be given to said strip of metal, and as will be readily understood said strip may be curved in the form of a true circle by maintaining the tool 36 and its supports in a fixed adjusted position, or said strip of metal may be formed into an elongated or elliptical shape by giving to said tool a suitable oscillating movement imparted through the medium of the cam 18 and member 26, the character of said elliptical shape being determined according to the adjustment of the screws 3037 and the position of the pin 27 within the slot 28. Looking at Fig. 2 of course it will be understood that the strips of metal may be fed in at the right side of the machine and discharged at the left as shown. The table or bracket 49 it will of course be-understood is mounted upon the plate 44: by the bolt 50 provided with a nut or other suitable binding means such as 51, so that it will be observed by loosening the nut 51 the table or bracket 49 may be adjusted upon the bolt 50 at any desired position.

Of course it will be understood that various modifications may be made without departing from the spirit of the invention as claimed.

I claim:

1. In an apparatus of the class described, a pair of forming rolls and guides at the rial to be formed thereby, a tool at the dis' charge side for additionally forming said I material, means for adjusting said tool, said means comprising a swinging bracket which may be thrown in and out of position for the insertion or removal of said tool, and means for adjusting said rolls longitudinally and transversely.

3. In an apparatus of the class described, a pair of forming rolls and guides at the feeding side of the same for guiding material to be formed thereby, a tool at the discharge side for additionally forming said material, means for adjusting said tool, said means comprising a swinging bracket which may be thrown in and out of position for the insertion or removal of said tool, means for adjusting said rolls longitudinally and transversely, and also means for automatically changing the position of said tool with respect to the position of said rolls as said material is being formed.

4. In an apparatus of the class described, a pair of forming rolls and a-guide at the feeding side of the same for guiding the material to be formed thereby, a tool at the discharge side for additionally forming said material, and means for slidably adjusting said tool upon a support, said means comprising a movable support and an adjustable screw thereon which may be thrown in and out of position for the introduction or removal ofvsaid tool.

In testimony whereof I hereunto aifix my signature in the presence of two witnesses.
